Great video, small question though, as we cannot give 'NOT NULL' constraint while using the ALTER command when we are adding a new column, can we add the data into it while we are creating the new column using the ALTER table command.

Can you include multiple statements in one alter table or you need one for each? For example, can an ADD and a DROP be used under the same ALTER TABLE?
